This pic is not exactly as it seems. It is a Camaro, but before this it was a Titus/Godsall (Pontiac T/A Team) built customer car.
One of 6 cars constructed for the '69 season, it had a lot of trick parts. The Pontiac factory was giving a bit of help to the team and providing engineering advise and parts.
There is one train of thought that these cars were Camaros to start with, but they would have been body shells, and separate panels perhaps.
This particular car was supplied to Richard Brown, Canadian racer, and he campaigned it originally as a Firebird in orange from the 69 St Jovite race onwards, and later, 70 onwards as a Camaro, to legitimately use the Z/28 302, which the Pontiacs had been allowed to use in 68 and 69, as it helped get another manufacturer on board.
The car was raced as a Camaro by several subsequent owners, but when it was no longer deemed to be raceable it was stripped of the brakes and gauges (which went into a street car) no doubt the engine and gearbox found new homes, but the body was literally buried. It will not be unearthed.
I do not know who took this pic, but I ould like to graciously thank the rightful owner, and credit that person.
